Specification of Letters Patent.

Patented June 29,1920.

Application filed December 13, 1918. Serial No. 268,574.

To all whom it may concern:

Be it known that I, JosnrH URBANEK a subject of the Emperor of Austria, residln at Chicago, county of Cook, and State 0 Illinois, have invented certain new and use: ful Improvements in Non-skidding Devices for Wheels, of whichthe following is a specification.

This invention relates to improvements in vehicle wheels and particularly to. types adapted to be used in connection with lgh grade vehicles.

The pr1nc1pal object of the invention is to provide devices in the form of attachments which may be applied to a wheel of the ordinary type of construction, the device being adapted to prevent slippingI or skidding of the wheel upon an icy or 0 erwise slippery surface.

A further whereby the non-skidding devices are hmitedly movable within their holder so as to present a plurality of spurs adapted to make contact with the surface over which the vehlcle wheels travel.

These and other like objects are attained by the novel construction and combination of p'artshereinafter described and shown in the accompanying drawings, forming a materialpart of this disclosure, and in which- Figure 1 is a side elevational view showinga wheel made in accordance" with the invention.

Fig. 2 is a cross-sectional view taken substantially on the line 2-2 of Fig. 3, the cylindrical extension 35, however, being shown Fig. 3 is a fragmentary side elevational view and sectionalview showing the. construction of'the device. Referring to the drawings, that the wheel, which is of. the usual type of construction, comprises a ri 'd hub 10,v secured to the axle in any pre erred man-' ner and provided with a plurality of ra-"' dially extending s k 11, :fixed at their outer ends in the rl rii Circumjacent to the felly 12, is a 14 having inturned flanged edges 15'adapte to engage with the inner, edges 16 of a tread element 17, containing the usual pneumatic tube 18, all of the several parts bemg of the ordinary type of construction.

The invention com rises an annular band 20, having an inwar 1y flanged edge 21, secured by screws or like fastening 22 object is to provide means mesh wit 1 ally outward from plungers 43, having con-.

' normal position of the spurs 32 and .mg indicatedin Fig. 3, or around the peit.will be seen to the telly 12, the band bein equivalent in diameter to that of the ell and is formed with a plurality of equa y spaced cylindrical projections 24, its front-flanged edge 25 extending slightl outward beyond the inturned flanges 15 0% the wheel-rim.

This flange 25 is equal in diameter with a ring 26 superposed over the band 20 upon the o posite side, and between the ring 26 and an e 25 is a casing 28 substantially rectangu ar in cross section, extending outwardly'to a point approximately equal with the center 0 the inner tube 18, forming a continuous chamber around the wheel.

.Formed at its center are openings 30, in

which are slidably engaged stems 31, hav- 'ing upon their outer ends curved transprojecverse elements 32, terminating in v on the sides of tions 33-adapted to the stems 31 being gui b hollow cylindrical extensions 35, tonne with the base. of the projections 24.

Formed with, 01 secured to the stems,

central in their length, are transverse bars 36, having elongated heads 37, the'outer edges of the bars having rack teeth 38, and

normally p ogt n d, (lulss to coiled compression rings e no engagl with spur linens 40 rotatably mount d upon spindles 41 secured transversely in the ORSIDE 28. The teeth of the pinions other racks 42, extending laterical spur like heads 44, and guided by pro jections 45 extending radially-centerward from the outer walls of the casing 28 the riphery' of the wheel shown in Fig. 1, except at the lower part thereof, where the showing issuch as to indicate the spur 82 having been pressed radially inward against the spring 39, at which time obviously the spur points 44 will be extended outwardly, due to the action of the rack and pinions interme'shing therebetween.

It will also be clearly evident that the entire device may be readily removed by disconnecting the bolts22, and removing the rings 20 with the several parts assembled intact. t

Having thus described my invention what I claim as new and desire to secure by Letters Patent, is-- I A device of the class described comprisin a peripheral casing attached to the. side 0 the folly of a wheel,-said casing inclosing ditional stems adapted to, move radially through said large holes, horizontal bars rigid,to' the outer ends of said last-named stems, fingers on the ends of said bars adaptedto embrace the side walls of'said casmg, bars rigidly attached to said la'st-' named stems at about the midpoint of the latter and at riggt angles'thereto, vertical racks on the en of said last-named bars,

.the innermost pinions rotatably mounted in the side walls of said casing and meshing with said racks, extensions on said first-named stems having racks thereon, said last-named racks also meshing with said fpinions, pockets formed in the inner walls 0 said casing radially adjaeent each of said last-named stems, eans rigid to said pockets for guiding sai lastnamed stems, coiled springs surrounding said stemsbetween'said last-named bars and oints of said pockets, and means for attac ing said casing to the -felly of a wheel. v I

In. testimony whereof I have affixed my signature.
